Hi Kibrom Gebrehiwot, Unsure if you're still stuck here. What you can do is goto Manage Ambari > Versions > and update the HDP and HDP-UTILS URL's. You will be able to find your relevant URL's in your version document of ambari. Try to use the Public URL's if you have internet access. Thanks, Adnan Khan ... View more
